You know those “Saturday Night Live’’ skits that go on and on with neither purpose nor point, vainly attempting to defy the law of diminishing returns?

Well, imagine one of those sketches elongated to 90 minutes and you’ve got “Kurt Vonnegut’s Make Up Your Mind.’’

This exercise in labored whimsy traveled a long and tortured path on the way to its world premiere at SpeakEasy Stage Company, and every bump of that journey shows in the misshapen “Kurt Vonnegut’s Make Up Your Mind,’’ directed by Cliff Fannin Baker.
